Active Learning Exercise II Distinguishing Fact from Opinion (A Cognitive Skill) The topic of drugs often generates heated debate between people with different perspectives. When discussing controversial issues, it is helpful to make a distinction between statements of fact and statements of opinion. (A fact is a statement that can be proven true. An opinion is a statement that expresses how a person feels about an issue or what someone thinks is true.) Although it is also important to determine whether the facts are true or false, in this exercise simply mark "O" for opinion and "F" for fact to test your ability to distinguish between the two: _____1. Marijuana is now one of America's principal cash crops. _____2. Friends don't let friends drive drunk. _____3. People who use drugs aren't hurting anyone but themselves. _____4. Legalizing drugs such as cocaine, marijuana, and heroin would make them as big a problem as alcohol and tobacco. _____5. The number of cocaine addicts is small compared with the number of alcoholics. _____6. The American Medical Association considers alcohol to be the most dangerous of all psychoactive drugs. _____7. Random drug tests are justified for personnel involved with public safety (e.g., air traffic controllers, police officers, etc.). _____8. If parents use drugs, their children are more likely to use drugs. _____9. Mothers who deliver cocaine-addicted babies are guilty of child abuse. ____10. Alcohol abuse by pregnant mothers is one of the most important factors in mental retardation. ANSWERS: Because answers may vary, we recommend discussing your responses with classmates and friends. Listening to the reasons others give for their answers often provides valuable insights and help in distinguishing between fact and opinion.

Like the Visual Summary found at the end of each chapter in the text, this narrative summary provides a final opportunity to review chapter material. I. Understanding Consciousness Most of our lives are spent in normal, waking consciousness, an organism’s awareness of its own self and surroundings. However, we also spend considerable time in various alternate states of consciousness (ASCs), such as sleep and dreaming, daydreams, sexual fantasies, chemically induced changes from psychoactive drugs, hypnosis, and meditation. Consciousness has always been difficult to study and define. William James described it as a “flowing stream.” Modern researchers emphasize that consciousness exists along a continuum. Controlled processes, which require focused attention, are at the highest level of awareness. Automatic processes, which require minimal attention, are found in the middle of the continuum. Unconsciousness and coma are at the lowest level of awareness. II. Circadian Rhythms and Stages of Sleep Circadian rhythms affect our sleep and waking cycle so that disruptions due to shift work, jet lag, and sleep deprivation can cause serious problems. A typical night's sleep consists of four to five 90-minute cycles. The cycle begins in Stage 1 and then moves through Stages 2, 3, and 4. After reaching the deepest level of sleep, the cycle reverses up to the REM (rapid eye movement) state where the person often is dreaming. III. Theories of Sleep and Dreaming The exact function of sleep is not known, but according to the repair/restoration theory, it is thought to be necessary for its restorative value, both physically and psychologically. According to evolutionary/circadian theory it also has adaptive value. Sleep seems to be controlled by several neurotransmitters and by various areas of the brain. Three major theories attempt to explain why we dream: The psychoanalytic/psychodynamic view says dreams are disguised symbols of repressed anxieties and desires. The biological (activation-synthesis hypothesis) perspective argues that dreams are simple by-products of random stimulation of brain cells. The cognitive view suggests that dreams are an important part of information processing of everyday experiences. IV. Sleep Disorders Many people suffer from numerous sleep problems, which fall into two major diagnostic categories—dyssomnias (including insomnia, sleep apnea, and narcolepsy) and parasomnias (such as nightmares and night terrors). People who have repeated difficulty falling or staying asleep, or awakening too early experience insomnia. A person with sleep apnea temporarily stops breathing during sleep, causing loud snoring or poor quality sleep. Narcolepsy is excessive daytime sleepiness characterized by sudden sleep attacks. Nightmares are bad dreams that occur during REM sleep. Night terrors are abrupt awakenings with feelings of panic that occur during non-REM sleep. V. Drugs and Consciousness Psychoactive drugs change conscious awareness or perception. Drug abuse refers to drug taking that causes emotional or physical harm to the individual or others, whereas addiction is a broad term referring to a person’s feeling of compulsion to use a specific drug. Psychoactive drug use can lead to psychological dependence or physical dependence or both. Psychological dependence is a desire or craving to achieve the effects produced by a drug. Physical dependence is a change in bodily processes due to continued drug use that results in withdrawal symptoms when the drug is withheld. Tolerance is a physiological process whereby the user needs larger and more frequent doses of a drug to produce the desired effect. The major categories of psychoactive drugs are depressants, stimulants, opiates, and hallucinogens. Depressant drugs slow the central nervous system, whereas stimulants activate it. Opiates numb the senses and relieve pain, whereas hallucinogens produce sensory or perceptual distortions. Drugs act primarily by changing the effect of neurotransmitters in the brain. Drugs that act as agonists mimic neurotransmitters, whereas antagonists oppose or block normal neurotransmitter functioning. There are many reasons for drug use and abuse, which fall into the two main categories of environment and biology. VI. Additional Routes to Alternate States Daydreaming and sexual fantasies are common forms of mild ASCs. They serve many functions—primarily positive. Hypnosis is an alternate state of heightened suggestibility characterized by relaxation and intense focus. Hypnosis has been used to reduce pain and increase concentration, and as an adjunct to psychotherapy. Meditation is a group of techniques designed to focus attention and produce heightened awareness. Meditation can produce dramatic changes in physiological processes, including heart rate and respiration. Although the study of consciousness has waxed and waned among psychologists, the public has historically been very interested---particularly in ASCs. Among peoples of all cultures, ASCs (1) are part of sacred rituals, (2) serve social interaction needs, and (3) provide individual rewards. -139065-4762500 SELF-TESTS (Review & wRite) Completing the following SELF-TESTS will provide immediate feedback on how well you have mastered the material.
